Hi,

Between the bones of the back (vertebra), there is are intervertebral discs. These discs have different functions. The report states that there is degeneration (break down of these discs) as well as bulging (protrusion) of the discs as they lay between the vertebra.

There is central stenosis (narrowing) at one point (narrowing of a central area of the bone which may then affect the nerves passing through) and also narrowing at another area which may also have an effect on the nerves there.

Most of these changes are chronic, meaning that they would have been going on for a long time but the fall may have aggravated it.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Michelle Gibson James,
General & Family Physician
